[patch] glibc-2.3.2 fails to compile on Linux with recent 2.5 kernels

[Bruce Allan]

Sorry if this has already been discussed/fixed, but I can't check the
mailing list archives since sources.redhat.com is currently down.  

Recent (in the last couple months) changes to the Linux 2.5 kernel cause
glibc-2.3.2 to fail to compile.  The problem is the new user pointer
annotations used in linux/sysctl.h and defined in linux/compiler.h
(normally included via linux/kernel.h).  The following patch fixes this:

Of course, an alternative in glibc's sysctl.h would be to:
#define __user
prior to including linux' sysctl.h
